Abstract

The environment and public health are strongly threatened by the accumulation of heavy metals (HMs) within the drinking water systems and the food chain, resulting from various anthropogenic activities. Thus, effective, reliable, and cost-effective methods for heavy metal decontamination ought to be developed and deployed for the mitigation of the HMs issues that lead to various environmental and public health problems. Chalcogenide nanomaterials have emerged as visible light photocatalysts used in heavy metal decontamination. The photocatalytic degradation process was preferred over adsorption and ion exchange as it does not produce any secondary pollution. This chapter, therefore, presents an overview of various chalcogenide nanomaterials used for heavy metal decontamination, challenges and future perspectives are also discussed.
